Two groups demonstrate designs for electrocaloric cooling that change temperature under an electric field

Two teams working independently of each other have demonstrated designs for electrocaloric cooling that can change temperatures under an electric field. Both groups used lead scandium tantalate capacitors in their systems, but they differed slightly in how they were used. The first group, with members from PARC in the U.S. and Murata Manufacturing Co., in Japan showed that electrocaloric cooling could be done using only solid materials. The second group, with members from the Luxembourg Institut...
